What is a homologous series?
उत्तर
A homologous series is a group of organic compounds having a similar structure and similar chemical properties in which the successive compounds differ by a \[\ce{CH2}\] group.
Example:
\[\ce{HCOOH}\] Methanoic acid
\[\ce{CH3COOH}\] Ethanoic acid
\[\ce{CH3CH2COOH}\] Propanoic acid
